Description

Die Erfindung betrifft eine Hülse zur Montage auf Tragzylindern von Druckmaschinen, mit zwei Flanschringen an den Enden der Hülse, an denen eine zylindrische äußere Hülsenwand und eine innere Hülsenwand im Abstand voneinander abgestützt sind, nach dem Oberbegriff von Anspruch 1.The invention relates to a sleeve for mounting on support cylinders of printing presses, with two flange rings at the ends of the sleeve, on which a cylindrical outer sleeve wall and an inner sleeve wall are supported at a distance from each other, according to the preamble of claim 1.

Die Erfindung betrifft insbesondere sogenannte Adapterhülsen für Druckmaschinen. Bei Druckmaschinen sind die Tragzylinder vielfach als Luftzylinder ausgeführt, auf die Adapterhülsen bzw. Arbeitshülsen nach dem Luftkissenprinzip axial aufgeschoben bzw. von diesen abgezogen werden können. Mit dem Druckluftsystem des Tragzylinders wird die Adapter- oder Arbeitshülse zur Montage oder Demontage geweitet, so dass sie während des Druckvorgangs mit Preßsitz auf dem Tragzylinder drehfest gehalten ist. Durch die Verwendung von Adapterhülsen kann vermieden werden, dass die jeweiligen Arbeitshülsen, die auf einem Tragzylinder mit vorgegebenem Durchmesser montiert werden sollen, übermäßig große Wanddicken erhalten, welche die Beschaffungskosten für die Arbeitshülsen erhöhen und die erreichbare Druckqualität mit den Arbeitshülsen mindern würden.The invention relates in particular to so-called adapter sleeves for printing machines. In printing machines, the support cylinders are often designed as an air cylinder, can be pushed axially onto the adapter sleeves or sleeves on the air cushion principle or deducted from these. With the compressed air system of the support cylinder, the adapter or working sleeve for assembly or disassembly is widened so that it is held against rotation during the printing process with a press fit on the support cylinder. Through the use of adapter sleeves can be avoided that the respective working sleeves to be mounted on a support cylinder with a predetermined diameter, receive excessively large wall thicknesses, which would increase the procurement costs for the working sleeves and reduce the achievable print quality with the working sleeves.

Adapterhülsen, die auf vergleichsweise einfache Weise an den Aufbau und die Abmessungen von Tragwalzen angepasst werden können und mit denen vergleichsweise gute Druckqualitäten erreicht werden können, sind beispielsweise aus der DE 20012929 U1 bekannt. Die Adapterhülsen umfassen hierbei zwei an den Enden der Adapterhülse angeordnete, inkompressible Buchsenelemente, deren Innendurchmesser mit einer Spiel- oder Übergangspassung größer ist als der Außendurchmesser des Tragzylinders. An den Buchsenelementen sind die aus Rohren bestehende innere und äußere Hülsenwand derart befestigt, dass die innere Hülsenwand im Montagezustand von der Außenwand des Tragzylinders um die Dicke von radial sich erstreckenden Buchsenabschnitten beabstandet ist, wobei beide Buchsenelemente endseitig mit Bundabschnitten versehen sind, an deren Außenfläche die äußere Hülsenwand anliegt. Die äußere Hülsenwand kann aus einem faserverstärkten Kunststoffmaterial bestehen. Alternativ kann die äußere Hülsenwand auch aus einem Aluminiumrohr oder einem anderen biegesteifen Material bestehen. Die Übergangs-oder Presspassung zwischen den beiden endseitigen, inkompressiblen Buchsenelementen bzw. Flanschringen und der Außenwandung des Tragzylinders kann durch Ausnutzung des Temperaturdehungskoeffizienten des für diese verwendeten Materials bei der Montage, durch hydraulische oder pneumatische Spannelemente oder durch Verwendung von Piezokeramiken erreicht werden.Adapter sleeves, which can be adapted in a relatively simple manner to the structure and dimensions of support rollers and with which comparatively good print quality can be achieved, for example, from DE 20012929 U1 known. The adapter sleeves in this case comprise two arranged at the ends of the adapter sleeve, incompressible female elements whose inner diameter is greater with a play or transition fit than the outer diameter of the support cylinder. At the sleeve members, the inner and outer sleeve walls made of tubes are fixed so that the inner sleeve wall in the assembled state is spaced from the outer wall of the support cylinder by the thickness of radially extending sleeve portions, both sleeve members being provided with collar portions at the outer surface thereof the outer sleeve wall rests. The outer sleeve wall may be made of a fiber reinforced plastic material. Alternatively, the outer sleeve wall may also consist of an aluminum tube or other rigid material. The transition or interference fit between the two end-side, incompressible sleeve elements or flange rings and the outer wall of the support cylinder can be achieved by utilizing the coefficient of thermal expansion of the material used for this during assembly, by hydraulic or pneumatic clamping elements or by using piezoceramics.

Die US 4,794,858 zeigt eine Adapterhülse mit zwei endseitigen Flanschringen und nur einem äußeren Hülsenmantel, wobei die zur Mantelfläche des Tragzylinders offene Kammer zwischen den beiden Flanschringen zur Übertragung des Druckluftsystems des Tragzylinders ausgenutzt werden soll. Die drehfeste Befestigung der Hülse auf dem Tragzylinder erfolgt mittels hydraulischen, dem Tragzylinder zugeordneten Spannelementen.The US 4,794,858 shows an adapter sleeve with two end flange rings and only one outer sleeve jacket, wherein the open to the lateral surface of the support cylinder chamber between the two flange rings to transfer the compressed air system of the support cylinder to be exploited. The rotationally fixed attachment of the sleeve on the support cylinder by means of hydraulic, the support cylinder associated clamping elements.

Aus der EP 683046B1 ist eine Hülse zum Montieren auf Trägerzylindern von Flexodruckmaschinen bekannt, bei welcher die äußere Hülsenwand von der inneren Hülsenwand durch zwei Flanschringe unter Ausbildung einer nach außen hin abgedichteten Kammer beabstandet ist, wobei die innere Hülsenwand zumindest auf einem Teilbereich elastisch verformbar ist und durch Beaufschlagen der Kammer mit einem geeigneten Fluid gegen den Außenmantel des Druckzylinders anpreßbar ist. Die gesamte Hülse kann hierbei aus einem Verbundwerkstoff hergestellt sein.From the EP 683046B1 a sleeve for mounting on support cylinders of flexographic printing machines is known in which the outer sleeve wall is spaced from the inner sleeve wall by two flange rings to form an outwardly sealed chamber, wherein the inner sleeve wall is elastically deformable at least on a portion and by applying the chamber with a suitable fluid against the outer shell of the printing cylinder is pressed. The entire sleeve can in this case be made of a composite material.

Die EP 1025996B1 zeigt eine Hülse mit einem Außenmantel aus einem Kohlefaser-Verbundmaterial mit einem gewickelten Gerüst aus Kohlefasern, wobei die Wicklung derart vorgenommen ist, dass die Hülse über die gesamte Hülsenlänge selbsttragend ist und zwei im Bereich beider Enden angeordnete Scheiben ausreichen, die aus der Kohlefaserwicklung bestehende Hülse vom Tragzylinder zu beabstanden. Die Wicklung der Kohlefasern muss der Hülse daher eine derart hohe Eigensteifigkeit verleihen, dass die Hülse über die gesamte Hülsenlänge, d.h. den Abstand zwischen beiden Scheiben, allen beim Drucken auftretenden Radialkräften standhalten kann. Bei Außendurchmessern von bis zu 400 mm beträgt die Wanddicke der mit der Kohlefaserwicklung versehenen Hülse bis zu 20 mm. Durch Verwendung eines kohlefaserverstärkten Verbundmaterials für die Hülse kann, im Vergleich zu Hülsen mit einem Mantel aus Metall, eine deutliche Gewichtsreduzierung erreicht werden.The EP 1025996B1 shows a sleeve with an outer sheath made of a carbon fiber composite material with a wound skeleton of carbon fibers, wherein the winding is made such that the sleeve over the entire sleeve length is self-supporting and two arranged in the region of both ends discs sufficient, consisting of the carbon fiber winding sleeve From the support cylinder to space. The winding of the carbon fibers must Therefore, give the sleeve such a high inherent rigidity that the sleeve over the entire sleeve length, ie the distance between the two discs, can withstand all radial forces occurring during printing. For outer diameters of up to 400 mm, the wall thickness of the sleeve provided with the carbon fiber winding is up to 20 mm. By using a carbon fiber reinforced composite material for the sleeve, a significant weight reduction can be achieved as compared to sleeves with a metal sheath.

Zwischen den Flanschringen sind Stützringe angeordnet. Die innere Hülsenwand besteht aus Wicklungen mit einem harzgetränkten Glasfaserband von etwa 1 Zoll Breite. Die äußere Hülsenwand besteht aus einer Wicklung mit einem kohlefaserverstärkten Gewebeband aus Faserverbundwerkstoff, wobei das Gewebeband derart angebracht wird, dass die Kohlefasern parallel zur Rotationsachse liegen.In the generic US 5,819,657 A different embodiments of sleeves for printing machines will be described. One of these embodiments provides a cylindrical inner sleeve and a cylindrical outer sleeve between which there is an intermediate layer. Another embodiment shows an inner sleeve with end-side flange rings on which an inner and an outer sleeve wall is supported. Between the flange rings support rings are arranged. The inner sleeve wall consists of windings with a resin-impregnated fiberglass tape of about 1 inch wide. The outer sleeve wall consists of a winding with a carbon fiber reinforced fiber composite fabric tape, wherein the fabric tape is mounted such that the carbon fibers are parallel to the axis of rotation.

Zwischen den beiden Flanschringen ist wenigstens ein die äußere Hülsenwand gegenüber der inneren Hülsenwand abstützender Stützring vorgesehen. Die Verwendung von Kohlefaser-Gelegen anstelle einer Kohlefaser-Wicklung führt zu einer beträchtlichen Minderung der Herstellkosten für die äußere Hülsenwand, da entsprechende Kohlefaser-Gelege, insbesondere Kohlefaser-Gelege mit unidirektionaler Anordnung sämtlicher Kohlefasern, vorfabriziert zugekauft und weiterverarbeitet werden können. Durch die Anordnung wenigstens eines, vorzugsweise mehrerer Stützringe zwischen den beiden Flanschringen kann bei äußerst niedrigem Gewicht und insbesondere äußerst geringer Dicke der äußeren Hülsenwand eine hohe Eigensteifigkeit der Hülse über ihre Länge erreicht werden. Die zusätzlichen Stützringe erhöhen zwar das Gesamtgewicht der Hülse, auf Grund der hierdurch ermöglichten dünneren notwendigen Dicke der äußeren Hülsenwand zeigt sich im Ergebnis jedoch, bei weiterhin niedrigem Gesamtgewicht der Hülse, eine überraschend hohe Druckqualität im Einsatz, die mit "selbsttragenden" äußeren Hülsenwänden, die nur endseitig abgestützt sind, nicht erreicht werden kann. Mehrere Lagen der Kohlefaser-Gelegen weisen dieselbe Faserorientierung auf. Ferner ist eine die Kohlefaser-Gelege umschließende Wicklung mit Kohlefasern vorgesehen, um die Eigensteifigkeit der äußeren Hülsenwand zu erhöhen.This object is achieved by the invention specified in claim 1. The outer sleeve wall consists of a fiber composite material with several layers of carbon fiber Geleges. Between the two flange rings at least one outer sleeve wall is supported against the inner sleeve wall Provided support ring. The use of carbon fiber lay-up instead of carbon fiber winding results in a significant reduction in manufacturing costs for the outer sleeve wall, as corresponding carbon fiber scrims, especially carbon fiber scrims with unidirectional arrangement of all carbon fibers, prefabricated and can be further processed. By arranging at least one, preferably a plurality of support rings between the two flange rings a high inherent rigidity of the sleeve can be achieved over its length with extremely low weight and in particular extremely small thickness of the outer sleeve wall. Although the additional support rings increase the overall weight of the sleeve, due to the thinner necessary thickness of the outer sleeve wall thereby made possible, however, results in a surprisingly high print quality in use, while the overall weight of the sleeve remains low, with "self-supporting" outer sleeve walls only supported at the end, can not be achieved. Multiple layers of carbon fiber lay-up have the same fiber orientation. Further, a carbon fiber cladding surrounding the carbon fiber wrap is provided to increase the inherent rigidity of the outer sleeve wall.

In bevorzugter Ausgestaltung sind zwischen beiden Flanschringen mehrere Stützringe angeordnet oder ausgebildet. Die Anzahl der Stützringe hängt hierbei maßgeblich von der Anzahl der Lagen an Kohlefasern bzw. Kohlefaser-Gelegen im Faserverbundwerkstoff und der Faserorientierung der jeweiligen Lagen ab. Bei der bevorzugten Ausgestaltung ist wenigstens ein Kohlefaser-Gelege vorgesehen, bei welchem die Faserorientierung der Kohlefasern 90° relativ zur Hülsenachse bzw. Tragzylinderachse beträgt. Diese Orientierung bewirkt optimale Festigkeitseigenschaften für die beim Druckvorgang aufzunehmenden Radialkräfte. Weiter vorzugsweise sind mehrere Lagen von vorzugsweise unidirektionalen Kohlefaser-Gelegen, insbesondere etwa 8 bis 15 Lagen Kohlefaser-Gelege vorgesehen. Die Steifigkeit der äußeren Hülsenwand läßt sich weiter erhöhen, wenn die Faserorientierung der Kohlefasern wenigstens einer Lage eines Kohlefaser-Geleges 45° relativ zur Hülsenachse beträgt. In einfachster Ausgestaltung können die Trägerfasern des Kohlefaser-Geleges im Prinzip keine bzw. nur eine geringe Festigkeitseigenschaft aufweisen und beispielsweise aus einem textilen Material wie Nähgarn bestehen. Bei der insbesondere bevorzugten Ausgestaltung weist auch die Trägerfaser des Kohlefaser-Geleges ausreichend hohe Festigkeitseigenschaften auf, wobei die Trägerfaser insbesondere aus einer Glasfaser bestehen kann. Bei der insbesondere bevorzugten Ausgestaltung besteht mithin die äußere Hülsenwand aus einem Glasfaser-/Kohlefasergelege-Hybrid. Besonders vorteilhaft ist, wenn - wie an sich bekannt- die Kohlefasern im Kohlefaser-Gelege bündelweise angeordnet sind und die Bündel mittels der Trägerfaser relativ zueinander positioniert sind. Jedes vorzugsweise flache, streifenförmige Bündel an Kohlefasern umfasst dann eine Vielzahl von Einzelfilamenten. Alternativ kann die äußere Hülsenwand auch aus Gelegen mit Kohlefasern und Glasfasern bestehen, wobei die Gelege dann mit wechselnden Faserorientierungen angeordnet sein können. Die die Kohlefaser-Gelege umschließende Wicklung kann aus einer endlosen Kohlefaser bestehen. oder es kommen bidirektionale Kohlefasergelege zum Einsatz. Die Matrix im Faserverbundwerkstoff, in das die Kohlefasern und weiteren ggf. die weiteren Verstärkungsfasern eingebettet sind, besteht vorzugsweise aus einem Ester, insbesondere einem Vinylester. Alternativ könnte auch ein Polyester oder Epoxydharz Verwendung finden.In a preferred embodiment, a plurality of support rings are arranged or formed between the two flange rings. The number of support rings here depends significantly on the number of layers of carbon fibers or carbon fiber layers in the fiber composite material and the fiber orientation of the respective layers. In the preferred embodiment, at least one carbon fiber scrim is provided in which the fiber orientation of the carbon fibers is 90 ° relative to the sleeve axis or support cylinder axis. This orientation provides optimum strength properties for the radial forces to be absorbed during the printing process. Further preferably, several layers of preferably unidirectional carbon fiber layers, in particular about 8 to 15 layers of carbon fiber scrim are provided. The stiffness of the outer sleeve wall can be further increased if the fiber orientation the carbon fibers of at least one layer of carbon fiber fabric is 45 ° relative to the sleeve axis. In the simplest embodiment, the carrier fibers of the carbon fiber scrim can in principle have no or only a low strength property and, for example, consist of a textile material such as sewing thread. In the particularly preferred embodiment, the carrier fiber of the carbon fiber scrim also sufficiently high strength properties, wherein the carrier fiber may consist in particular of a glass fiber. In the particularly preferred embodiment, therefore, the outer sleeve wall consists of a glass fiber / carbon fiber hybrid hybrid. It is particularly advantageous if - as known per se, the carbon fibers in the carbon fiber scrim bundles are arranged and the bundles are positioned by means of the carrier fiber relative to each other. Each preferably flat, strip-shaped bundle of carbon fibers then comprises a multiplicity of individual filaments. Alternatively, the outer sleeve wall may also be made of carbon fiber and glass fiber patches, which may then be arranged with varying fiber orientations. The winding enclosing the carbon fiber scrims may consist of an endless carbon fiber. or bidirectional carbon fiber covers are used. The matrix in the fiber composite material, in which the carbon fibers and further optionally the further reinforcing fibers are embedded, preferably consists of an ester, in particular a vinyl ester. Alternatively, a polyester or epoxy resin could be used.

Weiter vorzugsweise können bei den erfindungsgemäß eingesetzten Gelege die Fasern in gestreckter Form in jeweils einer Ebene liegen und durch mehrere Wirkfäden zueinander fixiert sein. Die Gelege können auch aus mehreren unterschiedlichen Rohstoffen und/oder aus mehreren hinsichtlich Orientierung und Flächengewicht unterschiedlich ausgeführten Lagen bestehen. Weiter vorzugsweise können die Trägerfasern, die die Fasern der Hauptorientierungsrichtung gemeinsam mit den Wirkfäden fixieren, auch aus Polymerfäden, Glasfaserrovings oder Kunststofffaserrovings bestehen.Further preferably, in the scrim used according to the invention, the fibers may lie in stretched form in each case in one plane and be fixed to one another by a plurality of knitting threads. The scrims may also consist of several different raw materials and / or of several layers of different orientation and basis weight. Further preferably, the carrier fibers which fix the fibers of the main orientation direction together with the knitting threads, also consist of polymer threads, glass fiber rovings or plastic fiber rovings.

Bei sämtlichen Ausgestaltungen ist die Hülsenaußenfläche vorzugsweise durch eine Funktionsoberfläche gebildet, wobei die Funktionsoberfläche insbesondere aus einer Beschichtung mit einem Metall wie Stahl, Aluminium, Nickel, Chrom oder Kupfer, einem Elastomer oder dergleichen besteht. Bei einer besonders bevorzugten Ausgestaltung ist die Funktionsoberfläche elektrisch leitend, wobei wenigstens ein Ableitelement zur Ableitung elektrostatischer Aufladungen in einem der Flanschringe angeordnet ist, welches im Montagezustand die Funktionsoberfläche mit dem Trägerzylinder verbindet. Das Ableitelement kann beispielsweise aus einem mittels einer Druckfeder vorgespannten Druckkörper bestehen, wobei sämtliche Funktionsteile des Ableitelementes elektrisch leitend sind.In all embodiments, the sleeve outer surface is preferably formed by a functional surface, wherein the functional surface in particular consists of a coating with a metal such as steel, aluminum, nickel, chromium or copper, an elastomer or the like. In a particularly preferred embodiment, the functional surface is electrically conductive, wherein at least one discharge element for discharging electrostatic charges is arranged in one of the flange rings, which in the assembled state, the functional surface connects to the carrier cylinder. The discharge element may for example consist of a biased by a compression spring pressure body, wherein all functional parts of the discharge element are electrically conductive.

Bei der insbesondere bevorzugten Ausgestaltung weisen die beiden Flanschringe einen endseitigen äußeren Flanschbund auf, der über eine äußere Mantelfläche des Flanschrings, an welcher Mantelfläche sich die äußere Hülsenwand abstützt, ringförmig übersteht und der die äußere Hülsenwand stirnseitig begrenzt. Besonders vorteilhaft ist, wenn die beiden Flanschringe auch einen endseitigen inneren Flanschbund aufweisen, wobei jeder innere Flanschbund über eine innere Wandfläche des Flanschrings, an welcher Wandfläche sich die innere Hülsenwand abstützt, ringförmig übersteht und die innere Hülsenwand stirnseitig begrenzt. Beide Maßnahmen begünstigen den Zusammenbau der Flanschringe, Stützringe und der beiden Hülsenwände.In the particularly preferred embodiment, the two flange rings on an end outer flange collar, which projects over an outer circumferential surface of the flange on which lateral surface, the outer sleeve wall is supported, annularly and limits the outer sleeve wall frontally. It is particularly advantageous if the two flange rings also have an end-side inner Flanschbund, each inner Flanschbund over an inner wall surface of the flange, on which wall surface, the inner sleeve wall is supported, projecting annular and the inner sleeve wall is limited end face. Both measures favor the assembly of the flange rings, support rings and the two sleeve walls.

Für Tragzylinder mit Druckluftsystem ist besonders vorteilhaft, wenn wenigstens einer der Flanschringe mit einem Bohrungssystem für das Druckluftsystem des Tragzylinders versehen ist. Das Bohrungssystem im Flanschring umfasst vorzugsweise wenigstens eine Radialbohrung mit einer Mündung an der Hülsenaußenwandung, wobei weiter vorzugsweise das Bohrungssystem wenigstens eine Axialbohrung aufweisen kann, die mit einem in eine Radialbohrung mündenden Zuführkanal in wenigstens einem der Stützringe verbunden ist. Die Axialbohrung des Bohrungssystems im Flanschring kann mit dem Zuführkanal im Stützring insbesondere über ein Leitungsrohr verbunden sein. Dies hat u.a. den Vorteil, dass die zwischen einem Flanschring und einem Stützring und/oder zwischen zwei Stützringen gebildeten Kammern nicht hermetisch abgedichtet sein müssen und dass die Verbindung zwischen den Flanschringen bzw. Stützringen und den Hülsenwänden nicht den Kräften des Druckluftsystems unterliegen. Falls mehrere Stützringe mit Zuführkanälen bzw. Radialbohrungen versehen sind, sind vorzugsweise die Zuführkanäle verschiedener Stützringe untereinander durch weitere Leitungsrohre verbunden. Um das Bohrungssystem im Flanschring mit dem Druckluftsystem des Tragzylinders zu verbinden , umfasst dieses bei der insbesondere bevorzugten Ausgestaltung eine Stichleitung zur inneren Hülsenwand, wobei diese mit einer umlaufenden Nut an der Innenseite versehen ist, in die die Stichleitung mündet.For support cylinder with compressed air system is particularly advantageous if at least one of the flange rings is provided with a bore system for the compressed air system of the support cylinder. The bore system in the flange ring preferably comprises at least one radial bore with an orifice on the sleeve outer wall, wherein more preferably, the bore system may have at least one axial bore which is connected to a feed channel opening into a radial bore in at least one of the support rings. The axial bore of the bore system in the flange can be connected to the feed channel in the support ring in particular via a conduit. This has the advantage, inter alia, that the chambers formed between a flange ring and a support ring and / or between two support rings do not have to be hermetically sealed and that the connection between the flange rings or support rings and the sleeve walls are not subject to the forces of the compressed air system. If a plurality of support rings are provided with feed channels or radial bores, the feed channels are preferably various support rings connected to each other by other pipes. In order to connect the bore system in the flange with the compressed air system of the support cylinder, this includes in the particularly preferred embodiment, a stub to the inner sleeve wall, which is provided with a circumferential groove on the inside, in which the stub empties.

Weitere Vorteile und Ausgestaltungen ergeben sich aus der nachfolgenden Beschreibung eines schematisch in der einzigen Figur gezeigten Ausführungsbeispiels.Further advantages and embodiments will become apparent from the following description of an embodiment shown schematically in the single figure.

In der einzigen Figur ist, in der unteren Hälfte geschnitten, eine auf einem insgesamt mit 1 bezeichneten Tragzylinder montierte Adapterhülse 10 dargestellt. Der Tragzylinder 1 umfasst an seinen beiden Enden jeweils einen Lagerzapfen 2 bzw. 3, mit welchen der Tragzylinder 1 in einer weiter nicht dargestellten Druckmaschine gelagert werden kann. Am Lagerzapfen 2 des Tragzylinders 1 ist ein Druckluftanschluß 4 mit einem Luftführungskanal 5 ausgebildet, der in einen hier zentrisch auf der Tragwalzen- bzw. Hülsenachse A angeordneten Luftkanal 6 im Tragzylinder 1 mündet. Der Luftkanal 6 erstreckt sich axial zumindest bis auf Höhe eines Querkanals 7 im Tragzylinder 1, welcher sich bis zur Umfangsfläche 8 des Tragzylinders 1 erstreckt. Derartig ausgebildete Tragzylinder für Druckmaschinen sind im Stand der Technik bekannt, sodass eine weitere Erläuterung hier nicht erfolgen muss.In the single figure, cut in the lower half, mounted on a generally designated 1 support cylinder mounted adapter sleeve 10. The support cylinder 1 comprises at its two ends in each case a bearing journal 2 or 3, with which the support cylinder 1 can be stored in a printing press not further shown. On the journal 2 of the support cylinder 1, a compressed air connection 4 is formed with an air duct 5, which opens into a centrally arranged here on the support roller or sleeve axis A air duct 6 in the support cylinder 1. The air duct 6 extends axially at least up to the level of a transverse channel 7 in the support cylinder 1, which extends to the peripheral surface 8 of the support cylinder 1. Such trained support cylinder for printing presses are known in the art, so a further explanation does not have to be made here.

Die erfindungsgemäße Adapterhülse 10 umfasst jeweils an den Enden einen ersten Flanschring 11 sowie einen zweiten Flanschring 12, an denen eine innere Hülsenwand 20 und eine äußere Hülsenwand 30 im Abstand voneinander festgelegt und abgestützt sind. Die Adapterhülse 10 besteht im Wesentlichen aus den beiden endseitig angeordneten Flanschringen 11, 12, den beiden Hülsenwand 20, 30 sowie mehreren Stützringen 40 bzw. 40A. Diese stützen zusammen mit den Flanschringen 11, 12 die beiden Hülsenwände 20 bzw. 30 gegenseitig ab und verleihen hierdurch der äußeren Hülsenwand 20 relativ zur inneren Hülsenwand 30 und zur Umfangsfläche 8 des Tragzylinders 1 über die Länge der Hülse 10 eine ausreichende Eigensteifigkeit zur Aufnahme der Druckkräfte beim Druckvorgang. Beide Flanschringe 11, 12 können vorzugsweise aus vergleichsweise formstabilen Kunststoff bestehen. Beide Flanschringe 11, 12 umfassen jeweils einen sich parallel zur Hülsenachse A über mehrere Zentimeter erstreckenden Ringsteg 13 bzw. 14, über dessen äußere Mantelfläche 13' bzw. 14' jeweils am endseitigen, äußeren Ende 15 bzw. 16 ein äußerer Flanschbund 17 bzw. 18 übersteht. Die äußere Hülsenwand 20 stützt sich jeweils unmittelbar an den äußeren Mantelfläche 13' bzw. 14' der Stegfortsätze 13, 14 der beiden Flanschringe 11, 12 ab und ist an diesen drehfest befestigt, beispielsweise mit diesen verklebt. Die beiden Flanschbunde 17 bzw. 18 liegen hierbei stirnseitig an der äußeren Hülsenwand 14 an und erstrecken sich bis zu dessen Außenfläche. Die innere Hülsenwand 30 liegt an inneren Mantelflächen 13" bzw. 14" der Stegfortsätze 13, 14, wobei auch über die inneren Mantelflächen 13", 14" jeweils ein innerer Flanschbund 17A bzw. 18A radial als Ringsteg nach innen hinausragt, so dass auch die innere Hülsenwand 30 bei montierten Flanschringen 11, 12 stirnseitig von den inneren Flanschbünden 17A bzw. 18A begrenzt ist. Die Stützringe 40, 40A sind vorzugsweise mit gleichbleibendem Abstand zueinander und zu den Flanschringen 11, 12 über die Länge verteilt angeordnet und die Stützringe 40, 40A können insbesondere aus einem formstabilen Kunststoffmaterial bestehen. Die Stützringe 40, 40A können auch aus vorgeformten Scheiben bestehen oder zwischen den beiden Hülsenwänden 20, 30 angeschäumt werden.The adapter sleeve 10 according to the invention comprises in each case at the ends a first flange 11 and a second flange 12, on which an inner sleeve wall 20 and an outer sleeve wall 30 are fixed and supported at a distance from each other. The adapter sleeve 10 consists essentially of the two end-mounted flange 11, 12, the two sleeve wall 20, 30 and a plurality of support rings 40 and 40A. These support together with the flange rings 11, 12 the two Sleeve walls 20 and 30 from each other and thereby give the outer sleeve wall 20 relative to the inner sleeve wall 30 and the peripheral surface 8 of the support cylinder 1 over the length of the sleeve 10 sufficient inherent rigidity for receiving the compressive forces during printing. Both flange rings 11, 12 may preferably consist of relatively dimensionally stable plastic. Both flange rings 11, 12 each comprise a parallel to the sleeve axis A over several centimeters extending annular web 13 and 14, on the outer surface 13 'and 14' respectively at the end, outer end 15 and 16, an outer flange collar 17 and 18th survives. The outer sleeve wall 20 is supported in each case directly on the outer circumferential surface 13 'and 14' of the web extensions 13, 14 of the two flange rings 11, 12 and is rotatably attached to these, for example glued to these. The two Flanschbunde 17 and 18 are in this case the front side of the outer sleeve wall 14 and extend to the outer surface. The inner sleeve wall 30 is located on inner lateral surfaces 13 "and 14" of the web extensions 13, 14, wherein also on the inner lateral surfaces 13 ", 14" in each case an inner Flanschbund 17 A and 18 A protrudes radially as a ring land inward, so that the inner sleeve wall 30 at mounted flange rings 11, 12 is frontally bounded by the inner Flanschbünden 17A and 18A. The support rings 40, 40A are preferably arranged at a constant distance from each other and to the flange rings 11, 12 distributed over the length and the support rings 40, 40A may in particular consist of a dimensionally stable plastic material. The support rings 40, 40A may also consist of preformed discs or between the two sleeve walls 20, 30 are foamed.

Die innere Hülsenwand 30 kann aus einem dünnwandigen Rohr aus Metall oder vorzugsweise aus elastisch verformbarem Kunststoffmaterial bestehen. Die äußere Hülsenwand 20 besteht erfindungsgemäß aus einem Faserverbundwerkstoff mit mehreren Verstärkungslagen eines unidirektionalen Kohlenfaser-Geleges 21 mit Kohlefasern, die in Bündeln 22 angeordnet sind, wobei bei wenigstens einer Lage die Faserorientierung der einzelnen Kohlefasern, wie in dem aufgebrochenen Ausschnitt der Hülse 10 dargestellt, senkrecht zur Hülsenachse A ausgerichtet ist, so dass die einzelnen Kohlefasern der Bündel 22 im Kohlefaser-Gelege 21 in der äußeren Hülsenwand 20 nach Art von Versteifungsringen angeordnet sind. Die äußere Hülsenwand 20 ist insbesondere als Kohlefaser-Glasfaser-Hybrid ausgebildet, wobei zusätzlich zu der bzw. den Kohlefaser-Gelegen 21 noch Glasfasern 23 in die beispielsweise aus Vinylester bestehende Kunststoffmatrix eingebettet sind. Die Glasfasern 23 können, wie im schematisch gezeigten Ausführungsbeispiel, unidirektional in ein Glasfasergelege 24 eingebettet sein, welches die Lagen an Kohlefaser-Gelegen 21 umschließt, oder die Glasfasern bilden die Trägerfaser für das Kohlefaser-Gelege 21. Die Faserorientierung der Glasfasern liegt vorzugsweise senkrecht zu den Kohlefaserbündeln 22 im Kohlefaser-Gelege 21 und mithin parallel zur Hülsenachse A. Die äußere Hülsenwand 20 umfaßt vorzugsweise bis zu zehn Lagen eines Kohlefaser-Geleges 21, wobei bei einigen Lagen die Faserorientierung auch 45° zur Hülsenachse A betragen kann. Die Anzahl der Lagen an Kohlefaser-Gelegen 21 und Glasfaser-Gelegen 24 und die Dicke der äußeren Hülsenwand 20 sind derart gewählt, daß die äußere Hülsenwand 20 unter den üblicherweise beim Druckvorgang vorliegenden Radialkräften verbiegen würde, wenn die äußere Hülsenwand 20 zwischen den beiden Flanschringen 11, 12 nicht durch die zusätzlichen Stützringe 40, 40A unterstützt wäre. Die Anzahl der Stützringe 40, 40A bestimmt sich mithin nach der Länge der Adapterhülse 10 sowie dem Durchmesser und dem Aufbau der äußeren Hülsenwand 20.The inner sleeve wall 30 may consist of a thin-walled tube of metal or preferably of elastically deformable plastic material. The outer sleeve wall 20 according to the invention consists of a fiber composite material with multiple reinforcing layers of a unidirectional carbon fiber Geleges 21 with carbon fibers, which are arranged in bundles 22, wherein at least one layer, the fiber orientation of the individual carbon fibers, as shown in the broken section of the sleeve 10, is aligned perpendicular to the sleeve axis A, so that the individual carbon fibers of the bundles 22 in carbon fiber Clutches 21 are arranged in the outer sleeve wall 20 in the manner of stiffening rings. The outer sleeve wall 20 is formed in particular as a carbon fiber-glass hybrid, wherein in addition to the or the carbon fiber-21 21 glass fibers 23 are still embedded in the existing example of vinyl ester plastic matrix. As in the schematically illustrated embodiment, the glass fibers 23 may be unidirectionally embedded in a glass fiber layer 24 enclosing the layers of carbon fiber layers 21 or the glass fibers forming the carrier fiber for the carbon fiber layer 21. The fiber orientation of the glass fibers is preferably perpendicular The carbon fiber bundles 22 in the carbon fiber scrim 21 and thus parallel to the sleeve axis A. The outer sleeve wall 20 preferably comprises up to ten layers of a carbon fiber Geleges 21, wherein in some layers, the fiber orientation may be 45 ° to the sleeve axis A. The number of layers of carbon fiber 21 and glass fiber 24 and the thickness of the outer sleeve wall 20 are selected such that the outer sleeve wall 20 would bend under the radial forces normally encountered in printing when the outer sleeve wall 20 is between the two flange rings 11 12 would not be supported by the additional support rings 40, 40A. The number of support rings 40, 40A is therefore determined by the length of the adapter sleeve 10 and the diameter and structure of the outer sleeve wall 20th

Aus der Fig. ist ferner ersichtlich, daß die Adapterhülse 10 an der Außenfläche mit einer Funktionsoberfläche 25 versehen ist, welche sich über die gesamte Länge der Hülse 10 erstreckt und sowohl die Außenwandung der äußeren Hülsenwand 20 als auch die Außenfläche der beiden Flanschbunde 17, 18 an den Flanschringen 11, 12 überdeckt. Die Funktionsoberfläche 25 besteht aus einer Beschichtung mit Metall oder einem Elastomer. Bei einer insbesondere leitenden Funktionsoberfläche 25 ist vorzugsweise in einem der Flanschringe, hier im Flanschring 12, ein Ableitelement 60 angeordnet, welches in einer Radialbohrung 61 angeordnet ist und sich von der Funktionsoberfläche 25 bis über die innere Hülsenwand 30 hinaus erstreckt. In bevorzugter Ausgestaltung umfaßt das Ableitelement 60 eine Hülse mit einem elektrisch leitenden Bodenstück 62 an welchem sich eine Feder 63 abstützt, mit der ein Druckkörper, vorzugsweise eine Kugel 64, durch eine Öffnung in der inneren Hülsenwand 30 hindurch gegen die Umfangsfläche 8 des Tragzylinders 1 gedrückt wird, so daß permanent ein elektrischer Kontakt zwischen der Funktionsoberfläche 25 der Adapterhülse 10 und der Umfangsfläche 8 des Tragzylinders 1 gewährleistet ist. Mehrere Ableitelemente 60 können hierbei über den Umfang verteilt bzw. über die Flanschringe verteilt angeordnet sein.From the Fig. It is further apparent that the adapter sleeve 10 is provided on the outer surface with a functional surface 25 which extends over the entire length of the sleeve 10 and both the outer wall of the outer sleeve wall 20 and the outer surface of the two Flanschbunde 17, 18th at the flange rings 11, 12 covered. The functional surface 25 consists of a coating with metal or an elastomer. In a particularly conductive functional surface 25, a discharge element 60 is preferably arranged in one of the flange rings, here in the flange ring 12, which is arranged in a radial bore 61 and extends from the functional surface 25 to beyond the inner sleeve wall 30. In a preferred embodiment, the discharge element 60 comprises a sleeve with an electrically conductive bottom piece 62 on which a spring 63 is supported, with which a pressure body, preferably a ball 64, pressed through an opening in the inner sleeve wall 30 against the peripheral surface 8 of the support cylinder 1 is so that permanent electrical contact between the functional surface 25 of the adapter sleeve 10 and the peripheral surface 8 of the support cylinder 1 is ensured. Several diverting elements 60 can be distributed over the circumference or distributed over the flange rings.

Für die Montage der Adapterhülse 10 auf als Luftzylinder ausgeführten Tragzylindern 1 ist die Hülse mit einem Luftleitsystem versehen, welches im gezeigten Ausführungsbeispiel eine Axialbohrung 71 und eine Stichleitung 72 im Flanschring 11 umfaßt, wobei die Stichleitung 72 in eine Umfangsnut 31 an der Innenseite der inneren Hülsenwand 30 mündet, welche im Montagezustand der Adapterhülse 10 auf dem Tragzylinder 1 der Querbohrung 7 im Tragzylinder 1 unmittelbar gegenüberliegt. Hierdurch kann die über den Druckluftanschluß 4 in den Tragzylinder 1 eingebrachte Druckluft in das Luftleitsystem in der Adapterhülse 10 eingeleitet werden. Da beim gezeigten Ausführungsbeispiel eine Arbeitshülse vom linken Ende der Adapterhülse 10 auf diese aufgeschoben werden soll, ist eine Axialbohrung 74 und eine Radialbohrung 75 im anderen endseitigen Flanschring 12 mit der Axialbohrung 71 im Flanschring 11 verbunden. Die Weiterleitung der Druckluft zwischen den beiden Flanschringen 11, 12 bzw. deren Axialbohrungen 71, 74 erfolgt über ein hier in mehrere Abschnitte unterteiltes Leitungsrohr 80. Dies hat den Vorteil, daß die zwischen den beiden Flanschringen 11, 12 und den dazwischen positionierten Stützringen 40, 40A ausgebildeten Kammern 27 nicht druckfest für Druckluft ausgeführt sein müssen. Im gezeigten Ausführungsbeispiel sind auf Höhe des Flanschrings 12 mehrere, umfangsverteilt angeordnete Austrittsöffnungen 76 vorgesehen, wobei jeweils im Bereich der Austrittsöffnungen 76 eine mit einem Durchgangsloch versehene Gewindeschraube 78 durch die äußere Hülsenwand 20 hindurch in den Stegabschnitt 14 des Flanschring 12 eingeschraubt sein kann. Weitere Austrittsöffnungen 77 können auch im Bereich eines oder mehrerer Stützringe 40 angeordnet sein, wobei dann wiederum eine Radialbohrung 79 von einem axialen Luftleitkanal 81 im zugehörigen Stützring 40 abzweigt und eine mit einem Durchgang versehene Gewindeschraube 78 durch die Hülsenwand 20 hindurch in den Stützring 40 eingeschraubt ist. Für die Positionierung und Ausrichtung der das Druckmotiv tragenden Arbeitshülse ist die Adapterhülse 10 mit einem sogenannten Passerstift 35 am entgegengesetzten Ende versehen.For the mounting of the adapter sleeve 10 designed as an air cylinder supporting cylinders 1, the sleeve is provided with an air guide system which comprises an axial bore 71 and a stub 72 in the flange 11 in the illustrated embodiment, the stub 72 in a circumferential groove 31 on the inside of the inner sleeve wall 30 opens, which in the assembled state of the adapter sleeve 10 directly opposite to the support cylinder 1 of the transverse bore 7 in the support cylinder 1. In this way, the introduced via the compressed air connection 4 in the support cylinder 1 compressed air can be introduced into the air control system in the adapter sleeve 10. Since in the embodiment shown a working sleeve from the left end of the adapter sleeve 10 is to be pushed onto this, an axial bore 74 and a radial bore 75 in the other end flange 12 is connected to the axial bore 71 in the flange 11. The forwarding of the compressed air between the two flange rings 11, 12 and their axial bores 71, 74 via a divided here into several sections pipe 80. This has the advantage that the chambers 27 formed between the two flange rings 11, 12 and the support rings 40, 40A positioned therebetween need not be pressure-tight for compressed air. In the embodiment shown, a plurality of circumferentially distributed outlet openings 76 are provided at the level of the flange 12, wherein in each case in the region of the outlet openings 76 provided with a through hole threaded screw 78 may be screwed through the outer sleeve wall 20 into the web portion 14 of the flange 12. Further outlet openings 77 can also be arranged in the region of one or more support rings 40, in which case a radial bore 79 branches off from an axial air duct 81 in the associated support ring 40 and a threaded screw 78 provided with a passage is screwed through the sleeve wall 20 into the support ring 40 , For the positioning and alignment of the printing motif carrying working sleeve, the adapter sleeve 10 is provided with a so-called registration pin 35 at the opposite end.

Für den Fachmann ergeben sich aus der vorhergehenden Beschreibung zahlreiche Modifikationen, die in den Schutzbereich der anhängenden Ansprüche fallen sollen. Falls der Tragzylinder nicht als Druckluftzylinder ausgeführt ist, kann ein Druckluftanschluß auch unmittelbar in einem der Flanschringe vorgesehen sein. Falls die Montage der Arbeitshülse von der Seite des Druckzylinder-Druckluftanschluß erfolgt, kann es ausreichend sein, wenn nur der benachbarte Flanschring sowie der erste, diesem benachbarte Stützring mit einem Luftleitsystem versehen ist. Die Anordnung und Anzahl der Kohlefaser-Gelege kann an die zu erwartenden Druckkräfte und die Anzahl der Stützringe angepaßt werden. Die Adapterhülse 10 kann nach dem Luftkissenprinzip oder durch andere geeignete Mittel drehfest mit dem Tragzylinder verbunden sein. Für die Montage nach dem Luftkissenprinzip kann beispielsweise die innere Hülsenwand kompressibel sein oder die innere Hülsenwand ist elastisch und im Bereich der Stützringe sind weitere Nuten angeordnet, wobei diese Innennuten einen Durchmesser aufweisen, der mit Spielpassung an den Außendurchmesser des Tragzylinders angepaßt ist.Those skilled in the art will recognize from the foregoing description numerous modifications which are intended to be within the scope of the appended claims. If the support cylinder is not designed as a compressed air cylinder, a compressed air connection can also be provided directly in one of the flange rings. If the mounting of the working sleeve from the side of the pressure cylinder compressed air connection, it may be sufficient if only the adjacent flange ring and the first, this adjacent support ring is provided with an air ducting. The arrangement and number of carbon fiber scrim can be adapted to the expected compressive forces and the number of backup rings. The adapter sleeve 10 may be rotatably connected to the support cylinder by the air cushion principle or by other suitable means.
